UNITED STATES PATENT OFFIC SAMUEL S. COLT, OF ORANGE, NEW JERSEY.

BEVEL AND MITER.

SPECIFICATION forming part of Letters Patent No. 322,906, dated July 28,1885.

\ 7 Application filed May 12, 1885. (N0 model.)

To all whom it may concern:

Be it known that I, SAMUEL S. COLT, a citizen of the United States,residing at Orange, in the county of Essex and State of New J ersey,have invented a new and useful Improvement in Bevels,of which thefollowing is a full, clear, and exact description.

My invention relates to an improvement, whereby the miter forming anyangle or bevel may be indicated by the instrument. I attain this objectby means shown in the accompanying drawings, in which- Figure 1represents a plan view in perspective of a bevel with my improvementsthereto, and Figs. 2 and 3 represent details of construction.

Similar letters refer to similar parts throughout the several views.

A is the body or handle of a bevel; B, the slotted blade, and b thethumb set-screw to hold the slotted blade B in position.

My improvements comprise the guide 0, as shown in Fig. 2, movablebackward or forward Within the slotted blade B, and held in position bythe thumb set-screw b, the blade B,with the guide 0, rotating on thethumb setscrew b, as shown. The guide 0 has a mark,

6, on the periphery forming the circular part to denote the position ofblade B with the scale D.

The ends of body or handle A are rounded off to form a half-circle andlaid out in spaces or degrees and numbered, forming a scale, as

shown at D and E. On the lower end of body or handle A is a blade, 0,which is held in position by the thumb set-screw a, and rotates thereon.The blade 0 has a mark, 02, on the edge to denote its position with thescale E.

To operate the instrument, when both blades B and 6 are closed up withinthe body or handle A, the mark 6 on the guide 0, within the slottedblade B, and the mark (1 on the edge of blade 0 will point to the number0 on their respective scales D and E. Then set the slotted blade B inposition with the body or handle A to form a right angle thereto. Setthe thumb set-screw b firmly. Turn the instrument to read the positionof the slotted blade B with the scale D, and note the number. Then setthe blade 0 -to the corresponding number on the scale E. Set up theset-screw a firmly, which will give the true miter, and a similar resultwith any angle or bevel that may be required.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The guide 0, the blade 0, set-screw a, scale D and E, index 6 and d, incombination with the handle A, slotted blade B, and setscrew 12, of abevel, all substantially as set forth.
